The whole is too wide for the sensor. Had to cut off the bolt and weld a new one to fit the sensor.

they generally only come with a wideband boss for aem ect
you can unscrew the narrowband boss from original elbow then just weld it into the pipe

if your going to use an aftermarket ecu such as power fc ect many of these don't use the narrowband lambda when being mapped as there mapped from idle all way through so youll only use the wideband

I had this problem with my downpipe so I found a bolt at work and cut the thread off it. I then tapped a thread down the centre for the lambda down the centre and welded it in.
